Basic Verification of Data Accuracy
To verify the number of shares, likes, comments, or total engagements for a specific URL, you can use the Facebook Debugger. This allows you to cross-check the values reported by Facebook and ensure that they align with the data from our API.
Privacy-Related Variations in SharedCount API Data
Due to privacy regulations, the data returned by the SharedCount API is intentionally approximate. A Gaussian blur (privacy-preserving statistical noise) is applied to engagement metrics such as shares, likes, and comments.
This means the values returned by the SharedCount API may differ slightly from the exact figures shown in the Facebook Debugger.
Examples:
If the actual share count (as shown in the Facebook Debugger) is 112, the SharedCount API may return a value in the range of 90–120
If the actual share count is 583, the SharedCount API may return a value in the range of 550–600
These ranges are intentional and reflect the privacy constraints imposed by Facebook.
